Computational simulation on VSC based on PID coordinated control algorithm and differential brake

摘要

The vehicle stability control system (VSC in short) is an advanced active safety system. The vehicle dynamic models are built with eight degrees of freedom, including vehicle body model, tire model, motor model, braking system model in Matlab/simulink. A two-DOF model is designed to compute nominal situation of the vehicle and control algorithms of vehicle stability control system based on PID control and differential brake are developed. Finally, computational simulations in four typical working situations according to the standard ISO-TC22/SC9 are made to analyze the vehicle stability control system.
